In order to work this out, the maximum ratings of both appliances are needed, as well as the meter position relative to this lot. Almost certainly, with typical appliances, one can say that 15mm tube over the distances mentioned are not enough.
The pipework should be designed so that the pressure drop between the outlet of the meter and the appliance does not exceed 1mbar at maximum flow conditions.
Option A *may* be adequate if the boiler is relatively small, but you would need to do the sums.
Same for Option B although again the calculations are required. This would likely be required for a larger or combi boiler, and I suspect the calaculations would show it to be belt and braces for a smaller boiler.
Option C seems similar to Option A.
Getting the pressures right is important both for operational and safety reasons.
From the perspective of doing any DIY work, the law requires you to be competent if you want to do your own fitting work, but does not define it. Professional fitters are required to be CORGI members.
There are a bunch of issues associated with installing a hob as well as installing a boiler that have to do with fitting arrangements, flues, ventilation and so on. The fact that the pipe sizing issue is probably wrong invites the question as to whether anything else is wrong.

Thanks so much for not saying "begs the question"
Do you think you could get hired to train BBC and other meejah folk in basic English?

God help us if he did. He would be gob-smacked touching base all over the place.
This "invites the question", could he do it with reverting to Little Middle Englandness?
From one who is incapable of correct spelling or grammar, or even constructing something resembling a sentence, that remark is nothing short of amazing.

It did "invite the question".
